"to be d'eliif'ered by mail are deposited, the invention having for anobject the provision of a novel discharge arrangement Afor the mail,which facilitates 'the removal of the inail from the box by thecollector.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will beliad to the following descriptionand accompanying drawing', and to the appended claims in which thevarious novel features of Ytheinventio'n are more particularly setforth.

F S is a fragmentary vertical sectional view taken on the line 8 8 ofFig. 5.

1n the drawing the reference numeral 10 shows a mail box of ordinaryshape and which is provided with an opening 10, closed by a hingedshutter 11, for the introduction of the mail into the box. The mail isdischarged from the box through a novel sectional door in the bottom ofthe box, this door being here shown as co-inprising a number of flatstrips which extend from side to side of the box and have their endsengaged with guide elements, such as shown at 14 in Fig. 8, extending'along the sides ofthe box from front to rear thereof. I have here shownfour of these strips which overlap one another, the front stripextending under the one to the rear of it. The front strip is numbered15 the rear strip is numbered 16 and the two intermediate strips areeach numbered 17. These strips lare yconnected together in a chain bymeans of pins 18 on -the strips 15, 17 which engage in slots 19 iii theends ofthe kstrips 17, 16.

To hold the rear strip against 'displacenient in a forward direction,and at the saine vtime to permit of its vertical adjustment as the ydooropens, this strip has a pair `of liea'ded'pins such as 2O fixed one to'each end thereof and engaging -in vertical T-guides 21 on the back ofthe box. Since the rear door sections are moved upwardly when'tlie dooropens, I may provide 'a sloping shelf 22 on the rear wall of the box10-and which is spaced upward from the bottom ofthe box just sufficientdistance to `accommodate '26 in the front 'strip 15 and which is formedon a bolt 27 slidable yalong the front wall of the box, there being apairof these bolts as release the hooked member from the door strip bymeans of an ordinary type of cram lock, each bolt having a spring' 28engaged therewith to hold it normally in operative position, or thesebolts may be arranged tobe released by an element carried upon a inailbag, as will be presently set forth.

The mail discharged from the box may be lcollected in a suitablyconstructed bag, a portion of which is indicated at 30, and which hasfitted to the mouth thereof a rectangular frame 31 of a length equal tothat of the box and which is adapted to engage in transverse guideelements 32 in the sides of the box under the discharge door thereof,and to engage the front strip 15 and open the door when the frame ispushed along said guide elements. As here shown the recesses 26 in thefront door section 15 are adapted to be engaged by pins 35 on bell cranklevers 36 fulcrunied as at 37 in recess 38 in the frame, these levershaving attached thereto cords 39 which lead around pulleys 40 andconnect to blocks 41 slidable in the frame and having projecting handles42 by pressing which latter toward one another the levers 36 areoperated to depress the pins 35 against the action of ex- 'will bein'idersto'od,which may be moved to 1 leasing the hooked members 25.

i tion 15, in which position the pins 35 are in registry with theapertures 34 in the said section, the pins springing into the apertureswhen the handles 42 are released. The frame 31 is then pushed inward,moving "f". the door section 15 ahead of itself, the other sectionsbeing successively moved until the parts assumeY the position sho-wn inFig. 5 v

with the door open for discharge of the mail. The frame 31 is thenpulled outward and causes the door to close, and operative engagementbeing effected between the frame and the door by the pins 85. After thedoor hasbee-n closed the pins 85 are re- .leased and the bag withdrawn,the door being then locked by a suitable key.

To ensure against rain accidentally entering the bag 30 I may providethe latter with a flap 31 which may be extended up the face of the boxand hooked at its upper end to eyes such as 46 on the latter.

Having thus described my invention what vI claim as new and desire toprotect by Letters Patent of the United States is as follows:

1. A mail box having a discharge door in the bottom thereof, said doorcomprising a number of sections overlapping at adjacent edges, and slotand pin connections between the respective sections whereby move-Yment'is transmitted from one section to another, the front sectionsengaging under the rear ones, headed pins on the rear edge of therearmost section, and vertical guide elements on the rear wall of thebox with which said headed pins engage.

2. In combination, a mail box'haviiig a discharge door in thebottoinvthereof nia-de up of a'number of sections overlapping atadjacent edges, a mail bag having rectangular frame at the mouththereof, guide elements on the sides of the box under the said door toreceive the said frame, and pins carried by said frame and adapted toengage in apertures in the front door section to establish an operativeclosing connection between the vframe andthe doo-r.

3. In combination, a mailbox having. a discharge door in therbottomthereof made up of a number of sections overlapping yat` VadJacentedges, a mail bag having a rectangular frame at the mouth thereof, guideelements on the sides of the box under the said door to receive the saidframe, and pins carried by said frame and adapted to engage in fapertures in the front door section to establisli an operative closingconnection between the frame and the door, levers on which said pinsaremounted., cords connected to said levers, and blocks slidable in theframe and having said co-rds attached thereto, said blocks havingprojecting handles.

In testimony whereof I have aiiixed my signature. Y
